I want to simulate an interfacial disorder of an FM/AFM bilayer, how can I implement this model in a program like Maple, Matlab or other magnetic simulation program (Mumax...)? Note: I can already simulate magnetization curves that have Exchange Bias.
You can e.g. have a system with 3 layers in MuMax3. The bottom layer, which represents the bulk antiferromagnetic spins, is frozen in a certain direction and is exchange coupled to a second layer. The second layer can rotate with respect to the fixed bulk AFM, takes into account the formation of a mauri domain wall in the AFM and interacts (through the exchange coupling) with a third layer which represents the ferromagnet. You can divide the 2nd layer into grains and vary anisotropy axis, coupling constant, anisotropoy constant,...
If you don't care about the Mauri domain wall energy, just use 2 layers: 1 represents the FM and 1 represents the uncompensated AFM layer. You can divide the AFM layer into several grains using the Voronoi tesselation.
